History of Vault

The Vault is the fourth encounter of the Last Wish raid, and has no boss fight. Fireteams must open the vault by removing duplicate symbols with the correct Taken Essence within three minutes.

Keep Out

The encounter's challenge, Keep Out, asks the team to kill each Might of Riven Knight before it reaches the central chamber. Once a fireteam member picks up the essence buff, Hive Knights spawn and rush the chamber: one after the first Captain dies, two after the second and three after the third. Two sections of the arena are sealed by a Taken wall when the essence is picked up, so players are usually assigned to the Tree, Rock and Ball rooms to catch the Knights. The Riven encounter comes next, with its own challenge.
